Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a cooling air conditioner.

[Conventional technology]

In the refrigerant circulation path of conventional cooling air conditioners, the structure for dissipating condensation heat is an air-cooled type with an air-cooled condensing means installed outside, as shown in the attached Figures 2 and 3. A water-cooled type with an outdoor heat dissipation tower is generally used.

With an air-cooled condenser (see Figure 2),
The high-temperature, high-pressure refrigerant compressed by the compressor 2 undergoes heat exchange with outdoor air in a condensing heat exchanger 131 provided outdoors. The cooled and condensed refrigerant is discharged to the evaporator 4 through the pressure reducing valve 5,
Indoor air is cooled by exchanging heat with the indoor air taken in through the intake window of the cooling air conditioner. The refrigerant after heat exchange returns to the compressor 2. The air cooled by the evaporator is sent into the room by the blower 6. Condensed water is generated on the surface of the evaporator 4, and is discharged to the outside of the air conditioner through the drain port 51 of the water collector.

In the case of a water-cooled condenser (see Figure 3),
The high-temperature, high-pressure refrigerant compressed by the compressor 2 undergoes heat exchange with water supplied from the water-cooling tower 41 in the water-cooled condenser 131 . After heat exchange, the cooling water returns to the external cooling tower and is cooled by the outside air.

[The problem that the idea attempts to solve]

In such a conventional air conditioner, in order to radiate the heat of compression to the outside, it is necessary to provide a separate heat radiating means outside the room, such as an air-cooled condensing means and a cooling tower. Therefore, installation work is difficult, especially in the case of high-rise buildings, where it is difficult to construct connection piping between the indoor main body and the outdoor heat dissipation means.
Installation costs will be higher. In addition, various obstacles may occur during installation due to lack of an appropriate installation location.

The present invention was developed in view of the above-mentioned problems, and uses air cooling and water cooling in combination as cooling and heat dissipation means for the condenser. Using a container, furthermore,
To provide a cooling air conditioner in which a heat dissipation means is integrated with a main body without reducing the cooling function of the cooling air conditioner by utilizing condensed water condensed in an evaporator as cooling water.

[Means to solve the problem]

In order to achieve the above object, according to the present invention, a compressor is installed inside a box having an intake window and an exhaust window.
A cooling air conditioner that has a refrigerant circulation structure consisting of a condenser, a pressure reducing means, an evaporator, and pipes connecting these, and a water collection unit that receives condensed water generated on the surface of the evaporator below the evaporator in a box. In the case where the condenser is a housing having a water tank section, a water supply hole, a drainage hole, and a water supply hole in the lower part, the condenser has an intake hole,
A condensing section consisting of an exhaust hole and a pipe disposed above the water tank inside the housing, one end of which is connected to a pipe leading to a compressor, and the other end connected to a pipe leading to a pressure reducing means. a water supply pipe having an air blowing means disposed inside the housing, and a pump, one end of which is connected to the water supply hole of the water tank, and the other end of which is connected to the condensation part inside the housing. A duct that connects to the exhaust hole of the housing to the outside of the box, an intake pipe that connects to the intake hole of the housing to the outside of the box, and a duct that connects to the drain hole of the housing to the outside of the box. A cooling air conditioner is provided that includes a drain pipe leading to the water collector, and a water supply pipe having one end connected to the water collector and the other end leading to the water supply hole of the water tank.

[Effect]

When the cooling air conditioner configured as described above is operated, the cooling water sent by the pump from the water supply hole in the water tank section at the bottom of the housing is ejected through the water pipe onto the condensing section, and the inside of the condensing section and its interior are ejected. refrigerant. In addition, outside air is taken into the housing from the intake hole by the air blowing means in the housing, is sent to the condensing section, exchanges heat with the condensing section, and is discharged to the outside of the air conditioner from the exhaust hole through the duct. At this time, a portion of the water on the surface of the condenser is further vaporized by the air flow, removes the heat of vaporization from the condenser, and is discharged to the outside of the air conditioner together with the air flow. The cooled and condensed refrigerant is sent to the vaporizer, where it exchanges heat with indoor air.

Since the surface of the evaporator that cools indoor air is cold, condensed water forms. The condensed water falls into the water collector, is supplied from the drain port through the water supply pipe to the water tank, and is used as cooling water.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side sectional view of a cooling air conditioner according to the present invention, and reference numeral 1 indicates the cooling air conditioner.

The high-temperature, high-pressure refrigerant compressed by the compressor 2 in the box 11 of the cooling air conditioner 1 flows through a pipe connecting the compressor 2 and the condensing section 33 of the condenser 3, and reaches the condensing section.

The condensing part 33 is located in the housing 38 above the water tank part 37 at the lower part of the housing. Pump 31 from water supply hole 311 of water tank section 37
2 is ejected through the water pipe 31 onto the condensing section to cool the refrigerant in the condensing section. A nozzle 32 is provided at the end of the water pipe as required. The condensing part 33 and the water tank part 37 are provided so that the cooling water falls from the condensing part to the water tank part below. A float valve 14 is provided in the drain hole 351 of the water tank section, and the water level of the cooling water drained through the drain pipe 35 connected to the drain hole and leading to the outside is maintained constant.

A blower means 30 is provided in the housing 38 to take outside air into the housing from the intake hole 361, and the condensing section 3 is heated by the taken outside air.
3 is cooled. The air blowing means 30 is a fan 301
and a motor 302 that drives the fan. After cooling the condensing section 33, the air is discharged to the outside of the air conditioner through the duct 39 leading from the exhaust hole 391 to the outside. At this time, a portion of the water on the surface of the condensing section is further vaporized by the blast of air, takes away the heat of vaporization from the condensing section, and is discharged to the outside together with the blast of air. Fins or the like may be provided in the condensing section in order to further increase the cooling efficiency by air heating.

The cooled and condensed refrigerant is discharged to the evaporator 4 through the decompression means 5 and becomes low temperature, and cools the indoor air by exchanging heat with the indoor air taken in through the intake window 12 of the cooling air conditioner. do. Since the temperature of the evaporator is low, condensed water is formed on the surface of the evaporator and falls into the water collector 8. Water supply pipe 3 from the drain of the water collector to the water tank
4 is provided, and the condensed water is supplied to the water tank section through the water supply pipe and used as cooling water.

The refrigerant after heat exchange returns to the compressor 2. The air cooled by the evaporator 4 is sent indoors by a blower 6 inside the box.

[Effect of idea]

Since the present invention is configured as described above, it produces the effects described below.

Since the cooling effect is further enhanced by the heat of vaporization of water when air cooling and water cooling are combined, the cooling and heat dissipation means of the condenser can be downsized, so the heat dissipation means can be used without reducing the cooling function of the cooling air conditioner. It can be integrated into the machine body.

Furthermore, by using the condensed water condensed in the evaporator as a heat dissipation means of the condenser, the condensed water that would otherwise only be discharged can be effectively used.
